He fell off a cliff but unexpectedly gained a cultivation inheritance.

Just as Zhang Bufan put the Youth-Preserving Pill formula jade slip into his storage ring, Yue Ling'er impatiently grabbed his sleeve, shook his arm, and said urgently, "Senior brother, senior brother, quickly take out the formula so we can see it! Can it really make people stay young forever?"

Liu Yan'er didn't move, standing to the side, her charming eyes filled with undisguised anticipation. Though she didn't ask a question, her slightly forward-leaning posture and focused gaze already revealed her thoughts. For female cultivators, no matter how high their cultivation level, it's hard to resist the temptation of eternal youth, especially for Foundation Establishment cultivators who can maintain their youth for decades. If they could use a youth-preserving pill to freeze their current appearance, it would be a dream come true.

Although Ye Qingxue was also curious, she was much more composed than the two of them. She gently tugged at Yue Ling'er's hand and whispered to Zhang Bufan, "Husband, why don't we take out the pill formula and take a look at the details first? That way we can know the difficulty of refining it and the materials required, so as not to be disappointed."

Zhang Bufan smiled and nodded, then took out the cyan jade slip again and handed it to Liu Yan'er: "Take a look first. Now that we have the pill formula, I will try to refine a few batches when I have time to fulfill your wishes."

Liu Yan'er took the jade slip, channeling a wisp of spiritual energy into her fingertip. The text and herbal illustrations on the prescription instantly appeared clearly in her mind. She read it carefully, her expression shifting from initial joy to regret. After a moment, she handed the jade slip to Ye Qingxue, sighing softly, "The auxiliary herbs required aren't particularly rare; they're mostly common hundred-year-old spiritual herbs. However, the three main ingredients all need to be over eight hundred years old. The most crucial one is the core ingredient, the 'Youth-Preserving Flower.' This thing is extremely rare. In all my years of cultivation, I've only ever seen it recorded in ancient texts. Such a high cost of refining it is truly not worth it compared to its effect of merely preserving youth."

Yue Ling'er leaned close to Ye Qingxue to examine the pill together. Upon hearing this, the joy on her face instantly faded, and she muttered with a droopy face, "It's so hard to gather all the materials, so it must be very difficult to refine it?" After reading the pill formula, Ye Qingxue nodded slightly. What Liu Yan'er said was true. Spiritual herbs over eight hundred years old were already a scarce reserve for various sects, and the Youth-Preserving Flower was unheard of. It would be extremely difficult to refine the Youth-Preserving Pill.

Zhang Bufan remained noncommittal upon hearing this, a faint smile still playing on his lips. High-aged spiritual herbs might be rare treasures for other cultivators in the Pangu World, but for him, they were readily available. The Xuanqing Secret Realm was rich in spiritual energy, far surpassing any other secret realm in the Pangu World. Around the spiritual streams and lakes grew a large number of spiritual herbs over a thousand years old, some even exceeding three thousand years, enough to meet the needs of the main ingredient in the Youth-Preserving Pill. Furthermore, the seemingly rare Youth-Preserving Flower grew in vast swathes along the shores of the spiritual lake in the Xuanqing Secret Realm, numbering in the hundreds, ranging from a hundred to a thousand years old—more than enough to refine hundreds of batches of Youth-Preserving Pills.

He suppressed his inner turmoil and smiled gently at Liu Yan'er, "Senior Sister, there's no need to feel sorry. I'll find a way to get the materials. If I can really gather the materials and refine the Youth Preservation Pill, I'll give you one, which will fulfill your wish."

Upon hearing this, Liu Yan'er was overjoyed and quickly bowed to Zhang Bufan to express her gratitude: "Thank you, Junior Brother! If I can really obtain a Youth Preservation Pill, I will definitely reward you handsomely!" Although she was extremely happy, she did not have high hopes in her heart—eight-hundred-year-old spiritual herbs and Youth Preservation Flowers were too rare. Even if Zhang Bufan was exceptionally talented, he probably would have difficulty gathering them. She took it as just a polite remark from Zhang Bufan.

Elder Liu, who was not far away, observed the interaction between the group. Seeing the female cultivators' enthusiasm for this useless pill formula, he shook his head helplessly, took a sip of the spiritual tea on the table, and then stopped paying attention, continuing to sort out the accounts. For a cultivator like him who was single-mindedly pursuing advancement in cultivation, the Youth-Preserving Pill was ultimately a product of unorthodox methods, far less practical than a pill that could help him break through.

Elder Ma Changsi walked over at this moment, his gaze falling on the jade slip in Zhang Bufan's hand. He smiled and said, "Bufan, although this Youth-Preserving Pill recipe is useless for cultivation, it's not a bad deal. Exchanging a bottle of spiritual spring water for a Xuan-rank pill recipe, if you encounter a female cultivator who likes to enhance her appearance in the future, you can exchange it for some more resources. It's not a bad deal."

"Elder Ma is absolutely right, that's what I think too," Zhang Bufan replied with a smile. Then, a hint of certainty flashed in his eyes. "Moreover, I believe this pill formula isn't entirely useless. I might be able to improve it, retaining its anti-aging effects while adding nourishing meridians and stabilizing Foundation Establishment cultivation. At that time, this pill will no longer be just a simple anti-aging elixir, but a Xuan-grade pill with practical value. Foundation Establishment female cultivators would probably spare no expense to fight for it, and its value would be immeasurable."

A hint of surprise flashed in Ma Changsi's eyes, clearly not expecting Zhang Bufan to have the idea of ​​improving the pill formula. He knew that Zhang Bufan possessed extraordinary talent in alchemy, and the quality of the low-grade pills he had previously refined far surpassed that of his fellow disciples. Perhaps he could truly achieve this. He nodded and praised, "Your talent in alchemy far exceeds that of ordinary people. Perhaps you can truly turn the rotten into the miraculous. If this succeeds, it will be a great thing for the sect. Whether for our own use or for exchanging resources, it will be of great benefit."

The two chatted for a few more minutes about the details of the resource exchange before Ma Changsi turned to count the remaining spiritual spring water and instructed his disciples to finish up. Zhang Bufan returned to the spiritual spring water shelf to continue assisting Ye Qingxue and Yue Ling'er in receiving the few remaining exchange customers. In his mind, however, he had already begun to consider specific ideas for improving the pill formula. In Xuanqing Daoist's inheritance, there happened to be several types of pill formulas that nourished the meridians, which might be able to be combined with the formula for the Youth Preservation Pill.

As the sun gradually set, golden rays filtered through the spiritual mist and spilled onto the corridor. The last few dozen kilograms of spiritual spring water at the Immortal Sword Sect's stall were completely sold out. Everyone went about their tasks, taking stock of the supplies they had obtained that day. After sorting through the inventory, the harvest far exceeded expectations: not only were there more than ten hundred-year-old spiritual herbs and five pieces of Xuan-grade refining materials, but also three Xuan-grade cultivation techniques, two Xuan-grade pill formulas, and several thousand mid-grade spirit stones. Although there were no thousand-year-old spiritual herbs or ancient treasures, it still replenished the sect's resources considerably.

The group handed over all the exchanged supplies to Elder Ma Changsi, who registered and stored them for safekeeping. They then returned together to the main hall of the Immortal Sword Sect, concluding their shift for the day. Inside the hall, Yue Buwei and True Person Wenshi were still chatting. Upon seeing the group return, they inquired about the day's exchange, and hearing of the fruitful results, offered their praise.

As night deepened, the spiritual mist in the Kunlun Secret Realm grew thicker, enveloping the entire realm in a hazy veil. The distant Tongtian Peak's spiritual light flickered in and out of sight, adding to its mystique. Inside the main hall of the Immortal Sword Sect, the lights shone brightly. Disciples were either meditating cross-legged or exchanging their observations of the day, creating a harmonious atmosphere.

Avoiding the crowd, Zhang Bufan walked alone to the window outside the main hall, took out the jade slip containing the formula for the Youth-Preserving Pill, and examined it carefully again by the moonlight. The text and diagrams on the jade slip were clearly visible, with the proportions of the three main ingredients and the core ingredient, the Youth-Preserving Flower, as well as the required refining temperature, all marked in great detail. He closed his eyes, rapidly processing the inherited knowledge of Xuanqing Daoist in his mind, comparing the Youth-Preserving Pill formula with the nourishing pill formulas in his inheritance, and pondering the possibility of merging and improving them.
